The present invention relates generally to cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom. In another embodiment, the present invention relates to an improved slurry hose and/or pipe for use in connection with cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom.

A cleaning pig assembly is provided for use on a tubular drag conveyor. The assembly is quickly and easily mounted anywhere along the cable, chain, or rope via slots in the assembly components. The components include a puck, a plate, a drag disc, and a cleaning member or tool sandwiched between the puck and the plate. The drag disc provides interference fit on the cable, chain, or rope holding the assembly on the cable, chain, or rope and prevents sliding of the assembly along the cable, chain, or rope during use. The cleaning assembly is installed without the use of tools or clamps. Multiple interchangeable cleaning members are provided depending on cleaning needs.

A conduit cleaning device includes a body with a central portion, a forward portion comprising a neck, and a rear portion with a hose fitting adapted for connection to an associated hose. The body includes a main flow passage that extends through the hose fitting, through the central portion, and into the neck. A rotor is rotatably supported on the neck. The rotor includes at least one rotor nozzle orifice in fluid communication with the main flow passage. A centering device is secured to the central portion of the body. The centering device includes a core and a plurality of fins that project outwardly from the core. The core of the centering device includes a mounting bore that extends therethrough, wherein at least part of the hose fitting is located within the mounting bore of the core and an annular space is defined between the hose fitting and an inner surface of the mounting bore of the core.

The method of using the flow within a pipeline to clean the inner wall of the pipeline including placing the cleaning pig into the pipeline to be cleaned at a first location, using a restraining rope or cable to cause the cleaning pig to move along the pipeline at a speed slower than the speed of the flow within the pipeline and thereby causing a pressure differential between the upstream side and the downstream side of the cleaning pig, providing one or more jetting nozzles and using the pressure differential to jet a portion of the flow within the pipeline through the one or more jetting nozzles onto the inner wall of the pipeline while providing a flow area through the cleaning pig to bypass the portion of the flow which does not pass through the one or more jetting nozzles.

There is provided a conduit cleaner including an elongate body. The cleaner includes at least one vane coupled to and extending radially outwards from a longitudinal axis of the elongate body. The at least one vane has a distal end portion shaped to abut against and clean an inner surface of a conduit. According to a second aspect, there is provided a conduit cleaner including an elongate body. The cleaner includes a plurality of turbines rotatably coupled to the elongate body. Each turbine includes at least one vane extending outwards from a longitudinal axis of the elongate body. The vanes have distal end portions shaped to abut against and clean an inner surface of the conduit.
